Joint Training for Learning Cross-lingual Embeddings with Sub-word Information without Parallel Corpora (2020.starsem-1)
Copied to clipboard
| Challenge: | Existing methods for learning cross-lingual word embeddings incorporate sub-word information during training. |
| Approach: | They propose a method that incorporates sub-word information during training to learn cross-lingual word embeddings from monolingual data and a bilingual lexicon. |
| Outcome: | The proposed method improves on bilingual lexicon induction, monolingual word similarity, and document classification using low-resource languages. |
Evaluating Sub-word Embeddings in Cross-lingual Models (2020.lrec-1)
Copied to clipboard
| Challenge: | Existing approaches to learning sub-word embeddings for out-of-vocabulary words have not considered sub- word embedds in cross-lingual models. |
| Approach: | They propose to use sub-word embeddings to form cross-lingual embeddables for out-of-vocabulary (OOV) words for which no embeddibles are available. |
| Outcome: | The proposed bilingual lexicon induction task shows that sub-word embeddings can be leveraged to form cross-lingual embeddables for OOV words. |
Evaluating a Joint Training Approach for Learning Cross-lingual Embeddings with Sub-word Information without Parallel Corpora on Lower-resource Languages (2021.starsem-1)
Copied to clipboard
| Challenge: | Cross-lingual word embeddings provide a way for information to be transferred between languages. |
| Approach: | They propose a joint training approach that incorporates sub-word information during training to learn cross-lingual embeddings. |
| Outcome: | The proposed method improves bilingual lexicon induction, especially for out-of-vocabulary words (OOVs) it is able to represent out- of-vocal words (OVs) and is more isomorphic than previous methods. |
